BOUT++: a framework for parallel plasma fluid simulations (2008)

Dudson, B. D., Umansky, M. V., Xu, X. Q., Snyder, P. B., Wilson, H. R.

A new modular code called BOUT++ is presented, which simulates 3D fluid equations in curvilinear coordinates. Although aimed at simulating Edge Localised Modes (ELMs) in tokamak X-point geometry, the...

HOXA1-stimulated oncogenicity is mediated by selective upregulation of components of the p44/42 MAP kinase pathway in human mammary carcinoma cells (2007)

Mohankumar, K.M., Xu, X.Q., Zhu, T., Kannan, N., Miller, L.D., Liu, E.T., ...

Expression of homeobox A1 (HOXA1) results in oncogenic transformation of immortalized human mammary epithelial cells with aggressive tumor formation in vivo. However, the mechanisms by which HOXA1...

Analysis of characteristic aroma of fungal fermented Fuzhuan brick-tea by gas chromatography/mass spectrophotometry (2007)

Xu, X.Q., Mo, H.Z., Yan, M.C.

Fuzhuan brick-tea is a popular fermented Chinese dark tea because of its typical fungal aroma. Fungal growth during the production process is the key step in achieving the unique colour, aroma and...

Microbiological analysis and antibacterial effects of the indigenous fermented Puer tea (2005)

Mo, H.Z., Xu, X.Q., Yan, M.C.

Microbiological analysis was done on samples from an indigenously fermented tea - Puer. Microbial counting and identification revealed that Aspergillus niger was the dominating microorganism during...

Characteristics of the H-mode pedestal and extrapolation to ITER (2003)

Osborne,T. H., Cordey,J. G., Groebner,R. J., Hatae,T., Hubbard,A., Horton,L. D., ...

The development of a predictive capability for the characteristics of the H-mode pedestal and ELMs is important in predicting tokamak reactor performance. The H-mode pedestal effects core confinement...

Overview of recent Alcator C-Mod research (2003)

Marmar,E. S., Bail,B., Boivin,R. L., Bonoli,P. T., Boswell,C., Bravanec,R., ...

Research on the Alcator C-Mod tokamak [1] is focused on high particle- and power-density plasma regimes to understand particle and energy transport in the core, the dynamics of the H-mode pedestal,...

Observations of the turbulence in the scrape-off-layer of Alcator C-Mod and comparisons with simulation (2003)

Terry,J. L., Zweben,S. J., Hallatschek,K., LaBombard,B., Maqueda,R. J., Bai,B., ...

The intermittent turbulent transport in the scrape-off-layer (SOL) of Alcator C-Mod [I.H. Hutchinson, R. Boivin, P.T. Bonoli et al., Nucl. Fusion 41, 1391 (2001)] is studied experimentally by imaging...

Experimental / theoretical comparisons of the turbulence in the scrape-off-layers of Alacator C-Mod, DIII-D, and NSTX (2003)

Terry,J. L., Zweben,S. J., Rudakov,D. L., Boedo,J. A., Hallatschek,K., Maqueda,R. J., ...

The intermittent turbulent transport in the scrape-off-layers of Alcator C-Mod, DIII-D, and NSTX is studied experimentally. On DIII-D the fluctuations of both density and temperature have strongly...

Evidence of Stochastic Diffusion Across a Cross-Field Sheath Due to Kelvin-Helmholtz Vortices. (1998)

Parker, S. E., Xu, X. Q., Lichtenberg, A. J., Birdsall, C. K.

We identify mechanisms for particle transport across a cross-field sheath. We present a study of E x B drift motion in a vortex in which the ion drifts are perturbed by their finite gyroradii and...
